gagement of gnidescarried by said plate with edges of. an innerrelatively: small=;plate. Witlis-ueh constructions, it has beennecessalyto make more or less expensiveprlovision for y connecting the sectionsofthe outer plate. It is an objeetof my invention however, to provide anew and improved construction in which both the outer relatively largeplate and the inner comparatively small plate, may Veach be of one-pieceformation.y In carrying out this end,a further aim is to provide a novelprocess of constructing a plate thimble, enabling the innercomparativelysmall plate to be properly engaged with the guides saidguides to said outer plate.

With the foregoing in view, the .invention resides in the novelsubject'matter hereinafterdescribed andv claimed, the description beingsupplemented by the accompanying drawing. Y

The form of the invention shownin Figs'. 1,l 2, 3 and 4 will first bedescribed. In these views, 7 denotes a flat sheet metal plate formedlwith va slot 8 and having its edges bent laterally to provide side andend flanges 9-10 respectively, saidv flanges all projecting in the samedirection and serving as means for spacing the body portion of the plate7y from a floor, Wall, etc. The corners of the,

plate are formedwithopenings 11y to re -ceive suitable attachingfasteners suchv las screws 12.

`I claim: Y' D 1. A device of the class described comprising a one-piecerelatively 'large outer plate formed 'with a slot .and` havingits edgesturned laterally in the same direction to provide side and end flanges,a one-piece A 7 constructions heretofore flanges, said inner platehaving an opening` for registration with said slot, and guides forslidably mounting said inner plate, said guides being secured to saidouter plate and lying against the inner side of said inner plate.

2. A structure as specified in claim 1; said guides being spaced fromsaid flanges and disposed in such spaced relation with one ofv saidflanges as to permit sliding of said, inner plate across the free edgeAoi? said one flange and into engagement with said guides uponlongitudinal springing of said inner plate, the resiliency of the innerplate i serving to snap it inwardly past said one fla-nge Vto a positionwithin the confines of said flanges, when moved inwardly to aysufficient extent.

.said plate being formed with a slot which extends longitudinally ofsaid plate, the end Y i peripheral flange to contact with a sup ort andspace the body portion ofthe plate rom said support, the Vcorners of theplate being formed with openings to receive attaching fasteners; arelativel small, one-piece, resilient sheet metal pllate lying againstthe central longitudinal portion of said outer plate and disposed at theinner side ofthe latter, said inner plate coveringsaid slot and beingformed with a pipe-receiving opening registering therewith, and stampedmetal guide` plates welded to theinner side of said outer plate betweenthe side flanges of the latter and said inner plate, theinner edges ofsaid guide plates `being oll'set and slidably receiving the longitudinaledges of said inner plate.

In testimony whereof I have hereunto affixed my signature.
